He said two monkeys were trained for the flight. At present, they are in quarantine. A launch of a monkey will be the first stage of a manned flight which will be carried out by Iran in 5-8 years, Fazeli said.

Since 2009, Iran has launched three satellites and a capsule carrying a rat, turtles and worms. An attempt to launch a monkey into space ended in failure in 2011.
